' 9; S ecificettion of Letters Patent. My!) 4 a P .l'rpplication filed August 1, 1813.

To all w/lom it mag concern it is the object of my invention to prov'de a scales especially lapted for use in far: in districts for the weighing of Wagon loads, such as loose ha or like material, requiring" the use of platform scales, such scales being o'lten iany miles distant from farms in the farming districts of the West.

in carrying out my invention I employ a, loaddilring; means which may take the form of a jack and which may he variously r-irranged with respectto the scale elements enacting therewith so that the scale ele ments oii'er yielding resistance to the liftinn means and indicate the "weight of the lifted load.

The distinguishing features of my inventicn and the improved structural elements charmrterising the practical embodiments which are illustrated as examples, will he more particularly explained in the specific description i cllciving.

Reference is to be had to the accompany ing drawings .ing a part of this speci i'icution in wlllClL similar characters oi reference indicate ccrrcsponding parts in all the us, and in which- I l 'igure l is a side elevation of a Weighing scales enihedving my invention; Fig. 2 is a vu'tical 1 eticnal view on a larger scale; Fig. a detail plan vievfof features to he hereinafter referred to: and l is u herizcntal section.

In constructin the illustrated practical mbodiment of the invention, the base formed with an inner cylinder 11 which rises Eliereircm and with an outer cylinder and a telescoping cylinder section 13 is arranged in ccnmu-ricn w th the cylinder The upper cylinder 13- is sustained by a spiral spring 1% .ilCll in the example shown is disposed at its lcw'er end between the said upper cylinder 13 and the inner cylinder 11. The spring .s held at its lower end by spiral flange 15 on the cyl inder ll beneath which the lower convolution of the spring is passed. A jack is pr0- sided, vvliicl in this instance is in the form the spindle 22.

of a jack screw 16 having a head 17 to he placed against a wagon axle, said head having the usual holes 1? to receive a turning lever. 'i he screw 16 operates in the head 18 of the cylinder 13.

In practice the cylinders 12 and 13 may ha e such strength and proportions that the outer cylinder will have sufiicient strength and be properly guided to sustain the load to which the jack is subjected. In the illustrated example I provide a guiding means additional to the cylinder 13, consisting of a depending member 19 having radial wings it) which have guided movement in radial slots 20 .of the head 20 formed on the inner cylinder 11. The arrangement is such that the device may be placed beneath a \VllfIOl] with the head I? or the jack directly beneath one of the axles,

and the turning of the screw will therefore result in forcing the cylinder 13 and its head 18 downwardly against the resistance of the spring ll. thereby 'arrying downward the depending member 19 until the resistance oi the spring is sullicient to sustain the load. after which the turningbf the screw will lift the load, thereby placing the latter on the spring. I

The indicating means of the scale ele- -ments are required to be only such as to indicate the extc'nt of movement of the cylinder l3 and its ap 'iurtenanees. in the present example there is a. movable element actuated bfv' the dmrnward movement or" the depending member 1%) 0n the head 18. and an. indicator to indicate the extent of move ment of the id element. Thus. a spindle is disposed cu-axially With the member l8. andon the lower end of said member a projection 21 is produced bearing agminst the upper end of said spindle The spindle has guided moi-'ement in approved means. such as brackets 2 l-25 suitably se mired to the cylinder 11 at the interior thereof, and surrounding said spindle is a compression sprin A pointer arm 26 responds to the movements of the spindle 22 and moves over the dial 2?. Movement in the present instance is imparted to t a pointer by a spindle 28 mounting said pointer. the spindle havinga drum 28 on which a cord 29 Winds. said cord passing over an idler 30 and being secured to an arm 31 on bus, as the spindle '22 is moved downward by the member 19 in reprovided with a head, a re and the pointer 26 thereof sponse'to the turning of when placed against the axle, the {13111, 31 thereof is carried downwardly end exerts a pull on the cord 29, thereby turning spindle 9.8 the same time the spring 28* on the spindle 28 is wound so that upon the member i9 rising,

- and the consequent raising of the spindle 22- by 1ts springf23, the coiled spring 28 will return the pointer to the neutral position and at the semetiine Wind in the slack of the cord 29.

In the use of the improved scales one of the devices will axle of the Wagon and the indicse'ed Weight having been noted, the device is applied beneat-h the front axle; the sum 01" the indicated W-SlgllllS will represent the total weight of the lead. A housing or anger may be provided around the dial and pointer, 2? and 26 respectively.
